Abstract
A jacking system for lifting a load step-bystep comprises two similar hydraulic climbing jacks 40, 401. A load (not shown) is attached to smooth rods 3, 31. The jacks are operated by a pump 20 which may be manually or power driven. Balancing hydraulic jacks 80, 801 are interconnected by a pipeline 24 and function as compensating means to prevent or correct any imbalance of the load on the rods 3, 31 such as may be caused by variation of the actual stroke of a jack from its nominal valve. In operation, prior to starting up the pump 20 to pressurize cylinders 4, 41 of main jacks 1, 11, the valves 11, 111 are opened to permit pressure transfer, cylinders 8, 81 of the balancing jacks 80, 801 being partly full of hydraulic fluid.
